Cubilose peptide as well as preparation method and application thereof

Abstract

The invention discloses cubilose peptide as well as a preparation method and application thereof, and belongs to the technical field of food processing. The cubilose peptide with low molecular weightand good flavor is finally obtained through secondary enzymolysis and protease type and dosage optimization. The preparation method of the cubilose peptide disclosed by the invention is simple and convenient in process flow, and the cubilose peptide prepared by controlling enzymolysis process conditions not only retains the original flavor of cubilose, but also does not have obvious enzyme flavoror peptide flavor, tastes soft and is not astringent. The cubilose peptide is low in molecular weight, easy to absorb and low in viscosity and can be used as a raw material to be suitable for food orskin care products, so that the preparation method of the cubilose peptide is suitable for market popularization and application and suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a bird's nest peptide and its preparation method and application. Background technique [0002] Bird's nest, as an ancient nourishing treasure and beauty product, has the functions of nourishing yin and lungs, nourishing and beautifying the skin, and at the same time, it can promote the metabolism of the human body. In recent years, with the increasingly active health food market, bird's nest products have become more and more popular among consumers. The main components of bird's nest are water-soluble protein, carbohydrates, calcium, phosphorus, iron, sodium, potassium and other trace elements and amino acids. Among them, the protein content in bird's nest is relatively high, about 49.9g of protein per 100 grams of dry bird's nest, and mainly Glycoproteins exist in the form of glycoproteins. With the growth of age, the protease secreted by the human body gr...

Problems solved by technology

The main components of bird's nest are water-soluble protein, carbohydrates, calcium, phosphorus, iron, sodium, potassium and other trace elements and amino acids. Among them, the protein content in bird's nest is relatively high, about 49.9g of protein per 100 grams of dry bird's nest, and mainly Glycoproteins exist in the form of glycoproteins. With the growth of age, the protease secreted by the human body gradually decreases. After the human body ingests protein, it is difficult to digest and the bioavailability of protein is not high. In the process of direct consumption of bird's nest, it is easy to cause damage to the nutrients in it. The absorption rate is low, which affects the edible effect

Therefore, in order to improve the absorption rate of protein peptides in bird's nest, there have been researches on the extraction technology of bird's nest small molecule peptides at this stage, but the flavor is not ideal, and the process is relatively complicated

[0003] And the preparation methods of existing bird's nest peptides mainly include enzymatic method and acid method. Although the enzymatic extraction has high efficiency because of its specificity, the final prepared bird's nest peptide tends to have enzyme flavor residue and astringent feeling, thus Affect the application range of the product; and in the acid extraction process, due to the intense reaction with the protein and the complicated operation process, the efficiency is low, and the deacidification is not clean.
